Well, 0day, kernelci etc... is nice... until the change is in the
driver. Most of the kernel are drivers, remember?

I don't know. I'd say that if patch is important enough for -stable,
there should be someone testing it. For core kernel changes, that can
be 0day bot, but for drivers...

And problem exists on mainline, too.

Hmm. Patch for obscure driver. Wow, nice, is WellKnownName actually
using that driver? Aha, no, he is not; he is doing global
search&replace, and did not test the patch...
